Claim of US Patent No. 10,694,494

1. A core network (CN) node comprising:a processor; and
a memory that stores processor-executable instructions, wherein the processor interfaces with the memory to execute the processor-executable instructions, whereby the CN node is operable to:
send, to a radio access network (RAN) node, a dummy paging request associated with a wireless device, wherein the dummy paging request includes information for use by the RAN node to calculate a time remaining until a next paging opportunity for the wireless device, and wherein the information comprises an International Mobile Subscriber Identity (IMSI) of the wireless device and an extended Discontinuous Receive (eDRX) cycle length of the wireless device; and
receive, from the RAN node, a dummy paging response which includes the time remaining until a next paging opportunity for the wireless device.
